In 1995, the World Health Organization (WHO) created an extra-governmental
organization, the Extra-Natural Activity Counter System (Encounters).
The purpose of this body is to investigate phenomena that cannot be
explained with existing scientific knowledge (which Encounter refers
to as "extra-natural activities"), research how they may
affect the health of humans and how the risk of future occurrences
can be managed, and plan measures to combat these phenomena.

To date, there have been hundreds of extra-natural cases reported--including
spontaneous combustion, abduction by aliens, the sudden appearance
of stigmata, the springing of fountains at sightings of the Holy Mary
such as Fatima and Lourdes, and the emergence of ectoplasm. However,
the organization has yet to come to a concrete conclusion regarding
any of these phenomena.
The organization's headquarters is located in The Hague, The Netherlands.
It has 20 branches across the world, of which the largest is the Japan
branch. This branch serves as the setting for the psychic-horror comic
book, "Encounters."

Sakuya Konohana

Nozomu Enjo

Okura Yamanoue

Due to her congenital inability to
feel pain or sweat, she has spent very little time outside of Encounter
and so has retained a pure, innocent mind. However, because she's
unaware of many of the things we call common sense, she also has the
ability to look at things from a fresh perspective. After discovering
that Enjo is her polar helix, she begins accompanying him and Okura.

The main character of the story,
his central philosophy is to live as normally as possible. Since being
abducted by aliens when he was 5, he's possessed powerful electromagnetic
properties. Enjo was initially the subject of investigations by Encounter,
but eventually ends up joining the organization after meeting Okura
and Konohana, to find the answers to the mystery behind his abilities.

Born in Mongolia, he spent his childhood
in Ulaanbaatar as a manhole child, one of many street children in
the country who shelter themselves in manholes, until he was abducted
by aliens. Following the incident, he was sent to Japan through Encounter.
He has the ability to seek out people who've been abducted by aliens.

Phenomenon01:
The aging incident
The first case that the three get involved in. On the way to Encounter
after being summoned there for a job, the teens witness the bizarre
phenomenon of the occupants of a subway train spontaneously aging.
But several hours later, all the victims have been completely cured.
This, it will turn out, is only the beginning of an even larger case.

Phenomenon02: The disappearing body
As the three enter the hospital where the victims of the aging incident
were treated, they catch a girl with fish scales all over her body
being hospitalized. It turns out this girl suddenly disappeared while
swimming in a local pool and reappeared 3 hours later at a nearby
park. However, when she comes to, she's lost all memory of the incident.
The high school trio suspects this has something to do with their
investigation.

Phenomenon03: Spontaneous combustion
Strange incidents start happening all over town. One man spontaneously
combusts, while a wolf at a zoo dies under mysterious circumstances.
Finally, children start disappearing one after another. When the high
school trio visits the home of a woman they suspect was a witness
to the aging incident, they finally start getting closer to the truth
of the matter. But at that moment, Konohana is abducted by a mysterious
being, prompting Enjo and Okura to go on a frantic chase in a bid
to rescue her...
